Three themes were covered :
- the immunogenicity of cancers and the factors involved in cancer evasion of the intratumoral immune response ;
- cancer immunotherapy using antibodies directed against regulatory molecules that remove the brake on the development of an effective immune response against cancer cells ;
- cellular and gene-based immunotherapy approaches for cancers capable of enhancing tumor cell elimination through the use of autologous T lymphocytes carrying a chimeric receptor against an antigen expressed by tumor cells (" CAR " T). This technique has proved effective in the treatment of leukemias and lymphomas involving B lymphocytes, by targeting the CD19 molecule present on the surface of B lymphocytes.
